Green Bay - Just like his players, Green Bay Packers offensive line coach James Campen watched every stomach-turning second of his unit's performance against the New York Giants.

Then he watched it again and again and again.

It was his job to go through the video and try to figure out why his group broke down in all five positions and let the Giants defensive line seep through the cracks like flood water at a basement window.

Some might suggest it's best to turn the page and put that one behind you.

"Absolutely not," Campen said Thursday. "You have to dissect it, look at it, analyze it, see what happened, why it happened and make the corrections. Players and myself have to be accountable and you move on from it.

"But you certainly don't brush it underneath the rug and say, 'Aw, heck, it's a bad day.' Or, 'gee, whiz,' or one of those deals. That's a loser's mentality. You have to identify it and make the corrections and move on."

Campen is the coach Packers fans want to fire most following the five-sack game on national television. Next week, it might be defensive coordinator Dom Capers or offensive coordinator Tom Clements or head coach Mike McCarthy, but this week it's Campen, who is the logical target when all five players play poorly.

In his sixth season as Packers line coach and ninth as a Packers assistant, Campen is no stranger to criticism. He got when he played poorly at center during his 61 games with the Packers, and he receives it as a coach whenever his line plays poorly.

He said it is better he draw the criticism when warranted than the praise when deserved.

"If we're sitting here and we've got zero sacks and zero pressures and zero hits and no penalties and everyone graded 100%, it's not me beating on my chest," he said. "I've never coached that way. It's about the player.

"If you're asking me if I felt like crap afterward, you're damned right I did. Do I absorb that, too? Yeah. Do I take accountability for that group? You're damned right I do."

Campen has not been dealt a fair hand this season, although he would never admit to it. General manager Ted Thompson kept just seven offensive linemen on the roster coming out of training camp, one of whom was Don Barclay, an undrafted free agent.

Thompson did not keep a backup tackle with a single game of NFL experience, dismissing media suggestions that he was paper-thin upfront. The only addition he made this season was to promote another undrafted rookie, Greg Van Roten, from the practice squad.

Then, when right tackle Bryan Bulaga went down with a right hip injury, left guard T.J. Lang was moved to Bulaga's spot and Evan Dietrich-Smith was moved to Lang's spot.

Barclay has been deemed unready for primetime, which means Campen was forced to move one of his best linemen to a spot he had played just once since the 2010 season.

In addition, Thompson rolled the dice that 2011 first-round pick Derek Sherrod would be available this season after a catastrophic leg injury, but on Tuesday, he was declared out for the season after barely stepping foot on the practice field. Were the Packers to suffer another injury, they'd be in a full-blown crisis.

Nevertheless, Campen takes responsibility for the Giants debacle and promised that his group would rebound.

"Those guys are true pros and they're accountable for their actions, as everybody in this locker room is," he said. "There's no such thing as wounded pride. Those guys are prideful men, and they have worked and displayed that time and time again and they will come out of this."

It is possible Campen has suffered from not having former offensive coordinator Joe Philbin, a former line coach himself, around. There was a reason Philbin was hired as the Miami Dolphins' head coach, and it had nothing to do with his looks.

But Campen played for veteran line coach Tom Lovat, worked under respected line coach Larry Beightol and grew together with Philbin under Mike Sherman and McCarthy. He was the line coach when the Packers won Super Bowl XLV.

He has been in this situation before and seen his group dig out of the mess. Anyone who says it doesn't take some resiliency to move on after such a poor performance doesn't know what it's like to be an assistant coach. There's a lot invested in the performance of the group.

"Each coach, when you're coaching a group, you're kind of living vicariously through your players," Clements said. "You want them to do well. When they do well, you're happy for them, but you feel good about it.

"When things don't go well, you're upset as well. You're just looking at the situation and trying to figure out what went wrong and what you can do to help your guys to perform up to their capability."

Veteran center Jeff Saturday said Campen has responded the way he would expect, which is to stay consistent with his teaching and not go into panic mode. He has not had to fly off the handle to get his point across.

"Just be consistent," Saturday said. "That's the most important thing."

In his assessment of what happened Sunday, Campen said he has to evaluate each player differently because the things Marshall Newhouse did wrong aren't necessarily the things Lang did wrong. It just so happened they both did them in the same game.

Newhouse, for example, got a little too aggressive and instead of sitting and waiting for the rusher to come to him, he punched early and got himself in a bad position. But the adjustments Newhouse has to make aren't necessarily the ones Lang or guard Dietrich-Smith need to make.

"Each person has different ways they tick," Campen said. "You can only look at yourself and figure out why it is happening.

Campen said all the criticism about how much pressure the line gave up against the Giants doesn't bother him because it is a really big deal to him. He used to be part of the group that helped protect Brett Favre, and now he's part of the operation that protects Aaron Rodgers.

He feels it anytime the quarterback gets hit.

"It's not just sacks; it's a hit or a pressure - it's a big deal," Campen said. "The quarterback has to be protected. We all know at times he's not going to be and there's going to be times he gets hit, but the frequency is too great. Yeah, it's a big deal."
